IMPROVEMENT IN LAMP-EXTINGUISHERS.

Specification forming part of Letters Patent No. 164,334,'dated June 8,1875; application filed April 14, 1875.

To all whom it may concern:

Be it known that I, JOHN O. SODERSTROM, of the city and county of Pepinand State of Visconsin, have invented a new and ImprovedLamp-Extinguisher; and I do hereby declare that the following is a full,clear, and exact description of the same, referencebeing had to theaccompanying drawing forming a part of this specification, in which-Figure 1 is a plan view; Fig. 2, a side elevation; Fig. 3, a sectionalelevation.

The invention relates to alamp-extinguisher, whose construction anddistinguishingfeatures will first be fully described, and then pointedout in the claims.

A represents a burner, and B a wick-tube. In the bell-shaped wick-tubecover 0 I arrange two opposite and oppositely concaved plates or jaws, DD, each resting against a rear spring, d, of any preferable form, oneworking within the other. Between and against these jaws work up anddown the outwardly-bent arms 6 c of a lever, E, said arms passingthrough holes 6, while the main stem is bent and pressed by a spring, F,at the point 6 The lever end is then bent upward and provided with aweight, H, sufliciently heavy to hold the plates or jaws D D apart afterthey have been once opened, but not heavy enough to counteract andovercome the tension of spring F when the jaws are closed.

The coal on the end of wick ordinarily militates very materially againstthe efficiency of ordinary extinguishers, but is of no consequence withmine; while mine is not alone thoroughly efficient in performing itsfunction of-extinguisher, but also is held at either of its twoadjustments without difficulty or chance of mutation.

Having thus described my invention, what I claim as new is- 1.The-opposite concave jaws D D, sliding one within the other over theburning wick, as and for the purpose specified.

2. The combination, with sliding jaws, of diverging arms 6 6, arrangedto vibrate on the inside of and unattached to said jaws, as and for thepurpose set forth.

3. The combination, with lever E, having arms 6 e, of end weight H andspring F, arranged to hold the jaws back from the wicktube, or allowthem to be slid over it by the spring.
